After the Second World War, the world was divided into two political poles. One of the poles consisted of liberal-capitalist countries led by the United States while the other block composed of communist countries led by the Union of Soviet Socialist Republics (USSR). That time, Turkey preferred to develop close relations with the Western world. Turkey, for example, became a member of the newly established United Nations. As a result of this preference, Turkey’s transition to multiparty politics was required. For this reason, in 1945, the establishment of new parties was allowed. The most powerful party established during this period was the Democrat Party (Demokrat Parti-DP). The four founders of the party, Celal Bayar, Adnan Menderes, Refik Koraltan and Fuat Köprülü, were members of the Parliament as the Republican People’s Party (Cumhuriyet Halk Partisi-CHP) deputies. In other words, the opposition was born in the CHP itself.
